The TWR figure represents the cumulative growth rate of your investment. Because many investments do not pay a consistent interest rate, but are rather the average of a what are special item numbers sins fluctuating market, the compound annual growth rate (CAGR) assumes compound growth over time to provide a projected rate of return. When saving and investing, this means that your wealth grows by earning investment returns on your initial balance and then reinvesting the returns. However, when you have debt, compound interest can work against you.
In reality, investment returns will vary year to year and even day to day. In the short term, riskier investments such as stocks or stock mutual funds may lose value. But over a long time horizon, history shows that a diversified growth portfolio can return an average of 6% annually.

Use the Bar Chart to Explore Growth Over Time
Compound interest is often compared to a snowball that grows over time. Much like a snowball at the top of a hill, compound interest grows your balances a small amount at first. Like the snowball rolling down the hill, as your wealth grows, it picks up momentum growing by a larger amount each period. The longer the amount of time, or the steeper the hill, the larger the snowball or sum of money will grow. You can use compound interest to save money faster, but if you have compound interest on your debts, you’ll lose money more quickly, too.

Simple interest refers only to interest earned on the principal balance; interest earned on interest is not taken into account. To see how compound interest differs from simple interest, use our simple interest vs compound interest calculator. The easiest way to take advantage of compound interest is to start saving! For longer-term savings, there are better places than savings accounts to store your money, including Roth or traditional IRAs and CDs. To illustrate the effect of compounding, let’s take a look at an example chart of an initial $1,000 investment. We’ll use a 20 yearinvestment term at a 10% annual interest rate (just for simplicity).

The question about where to invest to earn the most compound interest has become a feature of our email inbox, with peoplethinking about mutual funds, ETFs, MMFs and high-yield savings accounts and wanting to know what’s best.

With compound interest investments, it’s better to wait and allow these investments to grow, but with money you owe, it’s usually best to pay down debt as quickly as possible — especially if your interest rate is high. The MoneyGeek compound interest calculator uses a pie chart to show you the initial amount you contributed in purple, the total interest you earned in green and your total contributions in blue. With the compound interest calculator, you can switch the view to see a comprehensive breakdown in different formats.
The amount due increases as the interest grows on top of both the initial amount borrowed and accrued interest. Estimate your savings or spending through our compound interest calculator. Enter your initial amount, contributions, rate of return and years of growth to see how your balance increases over time. Use this calculator to easily calculate the compound interest and the total future value of a deposit based on an initial principal. The effective annual rate (also known as the annual percentage yield) is the rate of interest that you actually receive on your savings or investment aftercompounding has been factored in. Now that you understand how powerful compound interest can be, let’s break down how it’s calculated.
With the compound interest formula, you can determine how much interest you will accrue on the initial investment or debt. You only need to know how much your principal balance is, the interest rate, the number of times your interest will be compounded over each time period, and the total number of time periods. The compounding frequency, which is the time period at which interest is added to the principal, can have a slight positive effect on the effective interest rate versus the nominal annual interest rate. Using shorter compounding periods in our compound interest calculator will easily show you how big that effect is.
